ROBERT SEEGER, OF ST. PAUL, MINNESOTA.

GAS-REGULATOR.

SPEIPICATION forming part of Letters Patent No. 320,095, dated June 16, 1885.

Application filed February 25, 1885.

To all whom, it may concern:

Be it known that I, Ronnn'r SEEGER, a citizen of the United States, residing at St. Paul, in the State of Minnesota, haveinvented a new and useful GasRegnlator, of which the following is a specification.

My invention relates to improvements in gas-regulators in which a bell is floated upon a bath of glyeerine contained in a duplex cupshaped reservoir, with a stem connecting the bell with a valve, which by the rising and falling of the bell increases and decreases the supply of gas flowing through the regulator. The regulator is attached to the outlet-pipe of a gas-meter, and by adjusting the pressure on the bell by appropriate weights the flow of gas is regulated. I attain this object by the mechanism illustrated in the accompanying drawings, in which v Figure l is a side view of the regulator with all its parts in place. Fig. 2 is a vertical sectional view of the regulator, showing the various parts in position, the tubular support to the reservoir not being shown in section. Fig. 3 is a vertical sectional enlarged view of the socket or base, showing the position of the valve when the machine is at rest and no gas passing through the regulator. Fig. 4 is an enlarged plan view of the adjustable collar or ring 71..

Similar letters refer to similar parts through out the several views.

I make a duplex cup-shaped reservoir, A, of cast metal, having an outer shell and an in ner shell which resembles a cup turned bottom upward, and with the margin of the cup secured to the bottom of the outer shell, so forming a cylindrical well, I), which contains glycerine, and which said well has, by the form of the casting, no joints or scams exposed to the glycerine. The outer shell of the reservoir A is provided at the upper edge with a flange turned outward, to which is fitted a convex lid secured by screws (0. The upper horizontal surface of the inner shell of the reservoir A is perforated with a hole, to which is fitted, by means of a screw-thread, a tube of metal, E, connecting the reservoirA with the socket This tube E is provided with two guides, c c, which are perforated vertically and carry the valve-stem F. The upper end (N0 model.)

of the tube E is provided with a ring or shoulder, a, and the lower end with a ring or shoulder, (1, which shoulder makes with the screwthread below it a tight joint when the apparatus is put together. The lower end of the tube E is perforated near the bottom by holes 0, which admit of the escape of gas into the chamber f. The tube E, fitting closely in the collar S, makes when in place a gastight joint, which prevents the gas from escaping except through the valve. The lower extremity of the tube E is turned off square, presenting a sharp angle on its inner side. Inside of the tube E, and playing in the guides 00, is a valvestem provided at thetop with a screw-thread. At a convenient distance from the upper end of the stem I secure a washer, i, and on the washer t rests a bell-shaped vessel, D, made of sheet metal, of a cylindrical shape, and of a size convenient to slip over the inner shell of the reservoir A and Heat in the bath of glycerine held in the space between the two shells of the reservoir. This bell D is secured to the stem by the nut m, and rises and falls with the upward and downward motion of the stem F. The lower end of the stem F carries or holds the valve k-a circular piece of metal with the edge beveled, and is what is commonly known as a loose disk-valveconnected to the stem F by a ball-andsocketjoint.

The peculiar construction of this valvestem and tubular support is such that I can remove the valve-seat and the tube and replace it by a new valve or examine and clean it without disturbing the socket B from its connection with the meter.

The reservoir A and the stem or tube E are supported by a socket, B, made of hollow cast metal. The socket is of a pear shape, and the upper end of the pear has a perforation in it with a screw-thread cut for the reception of the thread of the screw toward the lower end of the tube E.

Midway in the socket B, and below the orilice of the outlet-pipe O, isa contraction of the casting, forming a collar, 8, which is turned out so that it exactly fits the turned end of the tube E, and the end of the tube E terminates just as it passes the said collar. The collar 8 divides the hollow space in the socket into two chambers-an upper and a lower. The lower end of the socket is provided with an opening gas-meter.

having a screw-thread on theinner side to enable it to be adapted to the outlet-pipe of a The outside of the lower end of the socket is octagonal in shape,forming a nut.

Within the end g, and working in the screw thread, is an adjustable collar, h, which is turned to raise it upward or downward by the mortise P. The object of the collar h is to form a support for the valve 70. It is screwed up or down, so that the base of the valve will rest upon it when at rest and prevent a flow of gas when'the bell Dhas dropped from a sinking of the glycerine or other cause.

In the side of the socket B, and communicating with the chamber f, is an outlet-pipe, 0, provided at the extreme end with an elbow and a screw-thread cut on the pipe to allow of its being attached to the supply-pipe of the gas-burner. d

Havingthus briefly'described my invention, I now proceed to explain the mode of operating the machine.

The parts being secured together, I remove the union-joint from the end of the outlet-pipe of an ordinary gas-meter. The socket B, by means of the nut end 9, is then secured on the outlet-pipe of the meter, and the union-joint I screw to the end of the pipe 0. The machine is then in place. I then fill the cylindrical well 6 with glycerine nearly to the top, which floats the bell D. Gas is then admitted from the meter, which, acting upon the bell D, raises the valve is into its seat. The pressure is regulated by the weight 2 on the bell D, and the opening of the Valve is varied in proportion as the number of burners used is increased or diminished, the gas-pressure from the main being constant. Through the aperture 6 gas has access to the chamber f, and thence passes into the outlet-pipe O,which conveys it to the burner.

The use of the machine greatly reduces the consumptionof gas by reason of the reduction and equalization of the gas-pressure, and the machine itself is more cheaply constructed and is much less difficult to operate than others in use.

The machine cannot become inoperative from changes of temperature, and can be regulated with the utmost ease by removing the cap of the reservoir A and adding or remov-' ing weights, as the case may be.

I am aware that prior to my invention gasregulators with afloating bell have been used, and I therefore do not claim the use of a gasregulator with a floating bell in the broad sense; but

What I do claim as my invention, and desire to secure by Letters Patent, is

1. In a gas-regulator, the combination of the socket B, having a contracted portion in the middle turnedout so as to admit of the passage through it of the valve seat end of the tube E, and the adjustable ring h, and outlet-pipe (1, combined with the valve bearing tube E, all as and for the purposes substantially as set forth and described.

2. In a gas-regulator, the combination of a basal socket, with adjustable collar or ring h, a contracted ring, 8, outlet-pipe 0, upper and lower chambers, A, vertical tube E, having a squared end, orifice e, valve 70, guide 0, stem F, a bell-shaped float, D, connected with the stem F, a duplex cylindrical reservoir of cast metal containing glycerine, all combined together, and arranged substantially as set forth and described.
